Bugfix: quasilit var read-print consistency.

The problem is that objects like `@{foo:bar} @{*xyz*}` are
printing as `@foo:bar @*xyz*` without the required braces.
This changes the meaning, as in @foo:bar which is @foo
followed by the text :bar, or creates a syntax error,
as in @*xyz*.

* lib.c (out_quasi_str): When printing a var, first convert
it to a string form by printing to a string stream. Then
if the string form consists of anything other than letters,
digits and underscores, mark it as needing braces,
in addition to the existing conditions.
